Answer:
dy/dx = (cos y + y sin x) / (cos x + x sin y)
Step-by-step explanation:
y cos x = x cos y
y (-sin x) + dy/dx cos x = x (-sin y dy/dx) + cos y
-y sin x + dy/dx cos x = -x sin y dy/dx + cos y
dy/dx (cos x + x sin y) = cos y + y sin x
dy/dx = (cos y + y sin x) / (cos x + x sin y)
Answer:
yo
Step-by-step explanation:
Answer:
x = 4 , y = 6
Step-by-step explanation:
I am sorry if I'm wrong
X=3
X/-3 = -1 ,Leave X by itself so multiply by -3 on both sides.
X = -1*-3
X = 3, negative times negative equals positive.
Answer:
<h2>

</h2>
Step-by-step explanation:
To find the value of x we can use either sine or cosine
Using cosine we have
<h3>

</h3>
From the question
x is the hypotenuse
4 is the adjacent
We have
<h3>

</h3>
We have the final answer as
<h3>

</h3>
